All about power locks from Service manual
This is not actually a write up but is a copy on power locks from the service manually. Felt so confused about them so when i found it though it might help clarify all the myths...
OPERATION
POWER LOCKS
All doors can be locked or unlocked mechanically and independently with their respective locking knobs. The front doors can also be unlocked by actuation of the inside remote door handle.
CENTRAL LOCKING/UNLOCKING (IF EQUIPPED)
The door locks can be locked or unlocked electrically via the exterior door key cylinders to provide the central locking/unlocking feature. The central locking/unlocking feature incorporates a customer programmable "Double activation unlock" feature which operates in the following manner: When enabled, the first turn of the key cylinder to the UNLOCK position (toward the front of the vehicle) will mechanically unlock the door whose key cylinder is being turned. A second turn of the key cylinder to the UNLOCK position (within five seconds of the first turn) will cause all vehicle doors and liftgate to unlock electrically. When this feature is disabled, all vehicle doors and liftgate will be unlocked electrically upon the first turn of a key cylinder to the UNLOCK position. The vehicle is locked electrically by turning the key cylinder to the LOCK position once, regardless of the state of the double activation unlock feature.
REMOTE KEYLESS ENTRY
The transmitter has three buttons for operation: LOCK, UNLOCK and PANIC.
Pressing the UNLOCK button will unlock the driver side door, flash the park lamps twice and enable illuminated entry. Pressing and releasing the button once will unlock the driver side door. Pressing and releasing the button two times within a five second interval will unlock all doors.
Pressing the LOCK button will cause the horn to sound a short chirp (if enabled) and flash the park lamps to notify that the all door lock signal was received and set. Illuminated entry is cancelled and the interior lamps are faded to off.
Pressing the PANIC button will cause the panic alarm to sound for three minutes, until the PANIC button is pressed a second time, or the vehicle reaches a speed of 25.7 Km/h (15 mph). The receiver is capable of retaining a Vehicle Access Code (VAC) even when power is removed. Each Remote Keyless Entry (RKE) module must have at least one and no more than four transmitters.
ROLLING DOOR LOCKS
When the rolling door lock system is enabled, the RKE module will automatically lock all the vehicle doors and liftgate when all of the following conditions are met:
All doors are closed
The vehicle speed exceeds 25.7 Km/h (15 1 mph).
The throttle position sensor tip-in is greater than 10 2 degrees.
The RKE module will automatically re-lock all doors if the above conditions are met and if any of the doors become ajar and then closed again.
The enabling/disabling of the rolling door lock feature is customer programmable, as well as programmable with the scan tool.
The power lock motors are also equipped with a thermal protection system which prevents the motors from burning out. The motors may chatter if they are continuously activated
STANDARD PROCEDURE - DOUBLE ACTIVATION UNLOCK
The toggling of the double activation unlock feature (between enabled and disabled) can be performed with the use of the scan tool, or by the customer.
SCAN TOOL PROGRAMMING
When using the scan tool, select:
1. “CCN”
2. “Miscellaneous Functions” and then the desired function.
CUSTOMER PROGRAMMING
1. Open the driver door, sit in the driver seat, and close the driver door.
2. Turn the ignition switch to the RUN position (without starting the vehicle) and then back to OFF. Repeat this step three additional times (for a total of four key ON/OFF cycles).
3. Within 10 seconds of switching the ignition switch to the OFF position for the last time (at the end of the fourth cycle in the above step), press the driver interior door lock switch to UNLOCK.
4. A single chime will be heard to verify that the customer programmable toggle of the double activation unlock was successfully completed.
Steps 2 and 3 must be completed within 10 seconds.
NOTE: When toggling the double activation unlock feature (customer programmable), the toggle that happens will be from the last state of the double activation unlock. If the double activation unlock feature was enabled, after the toggle process, it will now be disabled and vice versa. There is no telltale to inform you of which state the double activation unlock feature is in.
STANDARD PROCEDURE - ROLLING DOOR LOCKS
The toggling of the rolling door lock feature (between enabled and disabled) can be performed with the use of the scan tool or by the customer.
SCAN TOOL PROGRAMMING
When using the scan tool, select:

2. “VTSS”
3. “Miscellaneous” and then the desired function.
